Question

1,2(x-4)+6x5-1 1,2x ​

Answer 1

1,2x-4,8+30-11,2x
10x=25,2
X=2,52

Answer 2

To clarify your expression, it seems you have provided two separate parts: "1,2(x-4)" and "6x5-1 1,2x".

1. "1,2(x-4)": To simplify this expression, you can distribute the factor 1,2 across the parentheses:

1,2(x-4) = 1,2 * x - 1,2 * 4 = 1,2x - 4,8

2. "6x5-1 1,2x": There seems to be some ambiguity in this part of the expression. Please provide the correct formatting or clarify the intended operation between "6x5-1" and "1,2x."
